Tito Ortiz admits MMA fans could see something very special at UFC 148 this weekend, revealing there is no doubt Chael Sonnen has completely got under Anderson Silva's skin.

Ortiz appears in the co-main event on Saturday night, fighting Forrest Griffin in his final UFC bout. Usually the signing-off of a Hall of Famer would guarantee its own headline status, but Ortiz knows he is playing second fiddle to Silva v Sonnen.

After months of baiting, Sonnen has finally drawn a response from the unflappable champion, who promised to break the challenger's teeth. And Ortiz told ESPN he would love to get his Griffin fight over quickly so that he can see what unravels in the night's main event.

"It shows Chael Sonnen is getting under Anderson Silva's skin," Ortiz told ESPN. "Is it a good thing or a bad thing? We're about to find out.

"Anderson's feathers are ruffled and he's fighting out of anger now. I've never seen Anderson fight out of anger. To see him angry, out of character, he wants to kill Chael Sonnen."
